Abstract

Diplomsko delo obravnava dinamični model izvoda srednjenapetostnega omrežja, na katerem so priključeni porabniki in proizvajalci. V programskem paketu Matlab/Simulink je s knjižnico Powersys sestavljen dinamični model izvoda, ki omogoča izračun obratovalnih stanj. V modelu so uporabljeni osnovni elementi elektroenergetskega sistema, kot so: tuje omrežje, transformator, vodi, stikala ter porabniki in proizvajalci električne energije. Ker se v zadnjem času precej povečuje delež proizvodnje električne energije iz sončnih elektrarn, to pomeni, da se v distribucijskem omrežju pojavlja vedno več razpršenih virov. Model omogoča izračun optimalnega obratovanje teh virov in temelji na izračunih pretokov energije tako, da so izgube v omrežju minimalne.

Secondary title:	Electric power transmission in distribution networks with distributed generation
Secondary abstract:	This diploma work deals with the dynamic model of a middle voltage distribution network on which the consumers and producers are connected. The model is built in the software package Matlab/Simulink using library sym – Powersys. It makes calculation of operating conditions in the discussed middle voltage distribution network. The model consists of basic elements of the electricity network, like foreign network, transformer, transmission lines, switches, consumers, and electricity producers. Due to the recent significant increase of installed photovoltaic system the share of distributed generator in the distribution networks is increased as well. The proposed model is applied to determine optimal operating points of all distributed generation electricity production units in the discussed distribution network. The optimization is based on the load flow calculation. The goals of optimization are minimal losses in discussed distribution network.
